Grech RV, a leader in luxury Class B camper vans, announced significant advancements to its GRECH POWER energy platform for 2027 model year vehicles, introducing two new systems — GRECH POWER MAX and GRECH POWER CORE — engineered to deliver greater battery capacity, faster recharge capability, extended off-grid runtime and a more advanced connected user experience.
Building on the success of its fully integrated GRECH POWER platform, the 2027 systems evolve into a true Unified Digital Power & Control System — seamlessly integrating energy storage, charging, digital switching and remote connectivity into what Grech RV describes as an “Off-Grid Smart Home on Wheels.”
Developed in collaboration with Victron Energy, the new GRECH POWER MAX system will be featured on select 2027 model year STRADA-ion, TERRENO-ion and TURISMO-ion units. GRECH POWER MAX increases 51V lithium battery capacity from 16,896 watt-hours to 20,480 watt-hours — a 21% increase — delivering up to 16 hours of continuous A/C runtime and several days of uninterrupted off-grid power, depending on conditions and usage, the company said.
In parallel, Grech RV introduces GRECH POWER CORE on select 2027 model year VACANZA-ion units. GRECH POWER CORE increases battery capacity from 8,448 watt-hours to 10,240 watt-hours — also a 21% increase — delivering up to 8 hours of continuous A/C runtime and several days of uninterrupted off-grid power, depending on conditions and usage.
As part of this evolution, Grech RV is transitioning to a Victron-based battery ecosystem across 2027 model production moving forward, further unifying system integration, performance and user experience. The Victron Energy lithium batteries utilized within the GRECH POWER MAX and CORE systems are UL 2054 certified, reinforcing safety, reliability and compliance with rigorous industry standards. Availability of GRECH POWER MAX and CORE systems may vary by model, configuration and production timing.
A key component of the GRECH POWER platform is the integration of the Garmin SERV system, delivering advanced house control system. In combination with Garmin EmpirBus digital switching, this enables a fully integrated control environment across all critical RV systems.
“At Grech RV, power is no longer just a system — it’s the foundation of the entire ownership experience,” said AJ Thurber, vice president of Grech RV. “With our 2027 GRECH POWER™ MAX and CORE platforms, we’ve created a fully unified digital ecosystem that delivers more capacity, faster charging and intuitive control — transforming our vehicles into true off-grid smart homes on wheels.”
